In the interest of full disclosure, it makes sense to facilitate details for sold properties so that buyers & sellers have the benefit of the same information realtors, appraisers & mortgage lenders are able to access. Anyone can Zillow an address and get recent sold prices, with BR’s Baths and sq footage. Providing more details about the property’s condition, photos and extra features (or problems) makes the data more meaningful.
Isn’t that what the internet is all about?
